His 15-year-old friend, Darrin Wilson, was charged with reckless homicide and taken to juvenile detention.

Authorities believe that they were playing with the weapon around 3 a.m. on Tuesday morning at another friend’s house when the gun went off. They have closed the investigation into Robertson’s death.

However, the Shelby County District Attorney General Office has said that there would be an inquiry into how the teens got the guns, drugs and cash. Officers are looking at images showing a group of boys, including the duo, making apparent gang signs and holding up semi-automatic weapons.
